Convert cm to feet

Centimeter

التعريف
A centimeter (symbol: cm) is an SI unit of length equal to one-hundredth of a meter (0.01 m). It provides a convenient subdivision of the meter for everyday and scientific measurements.

الأصول
Built from the prefix centi- (Latin centum, “hundred”) and the base unit “meter,” the centimeter is part of the metric system’s decimal architecture. While the meter’s definition has shifted—from Earth-based to a light-speed standard—the ratio (1 cm = 0.01 m) remains fixed.

الاستخدام اليوم
Centimeters are used worldwide for measuring dimensions where meters are too coarse: heights, small distances, school rulers, and many laboratory applications outside the U.S.

Foot

التعريف
A foot (symbol: ft) is an Imperial and U.S. customary unit of length defined as exactly 0.3048 meters. One foot comprises 12 inches, and three feet make a yard.

الأصول
Historically, “foot” measurements varied (250 mm–335 mm) based on local standards and human anatomy. In 1959, countries using Imperial and U.S. customary systems agreed to standardize the foot at 0.3048 m.

الاستخدام اليوم
Feet remain standard in the U.S., Canada, and U.K. for architecture, personal height, aviation altitudes, and sports field dimensions.
